Set Up

.
Setting up guitars is hard. I think its one of the hardest things I do.

There's a popular idea among some players that they should be able to set their own guitar set up, if you're any good as a player then you should be able to do it. I don't agree with this.

There are so many factors which interact with each other it becomes a complicated task - everything interacts with everything else. Change one little thing and it all needs to be changed. Each extra element - string guage, tuning, player's approach, truss rod, nut height, required action, type of music, type of bridge, woods eg. increase the complexity exponentially.

I always like to have a chat with the player about their playing style and requirements. I often ask to see them play to get an idea how they attack the string with their plucking hand. I try and tailor a set up to the player, after all its not me that's going to be playing their guitar.

As well as making adjustments to get the most out of the instrument (and the player) I do a lot of extra stuff with a set up. Its all this extra stuff I'm going to talk about.
This is just what I did on this particular instrument - a Les Paul would have been treated differently. I can't think of a way to write comprehensively about set ups - even exactly the same model as this one might need a different approach. So this is just an example of what's involved, I adapt these techniques and use others as and when required.
I try and make my set ups as personal to the player as I can and this is an example of the extra stuff I do to try and achieve this.
I'm going to talk about setting up a Strat - although in this case its a Godin version of the Fender.


Check out www.myspace.com/georgeandqueen to hear this guitar in action.

The first thing to be done in the set up process is measure the action.
I need to know the starting conditions - if the player wants a higher or lower action I need to know where it was to begin with.





Then I strip the guitar down completely. On a Strat I spend a lot of time on the bridge.

Every screw needs to be removed, cleaned, lubricated and put back. On this bridge the small grub screws that adjust the saddle height on the bass strings were seized. They needed to be heated up to release them.



I have a stand to hold the bridge while working on it, there's a platform to hold the parts and a place for the tools. This speeds the process up and keeps everything in order.


This is the bridge after the work. Not only does it function better but it will last a lot longer too. With regular maintenance a Strat bridge should last for decades.



The body where the trem rests on it is vital to the bridge's performance - it needs to be clean and lubricated for the tuning to be stable.
The earth wire to the trem claw was disconnected on this guitar so I soldered it back on to the volume pot casing.

Next I buff the frets up to remove any corrosion and to help playing feel and tone. It is a joy to bend strings with highly polished fretwire - the string just glides.


There's a lot of wear in these frets but that's not my job today. I've already spoken with the owner about it and that's a job for another time
I mask the fingerboard off to avoid buffing the wood. I don't want to damage or stain the fingerboard.



The buffing arbour is a very useful tool - saves a lot of time and effort. Its geared down to run at 900rpm to stop things getting too hot. The pyramid shape makes it really stable - if you want to make something tall without it falling over that's the shape to make it - nothing new in that idea :-)


The final stage of the preliminary set up is to polish the body and neck. My favourite polish is 'Mr Glyn's Luthier's Finest'. It would be  - I make the stuff. It's available direct from me or www.guitarstuff.co.nz . It only needs a very light spray and it leaves no residue. The 125ml bottle pictured lasts me about 3 months so it will last you years.

So then its into the set up proper - stringing, truss rod adjustment


filing the nut slots with special files and setting the action, pickup height and intonation.


Typically this guitar also had loose strap hooks and jack socket. I often change pickup springs and solder loose wires.

All these little things get checked for and sorted out with a set up.

Here's my workshop check list I use when setting up electric guitars - the acoustic and bass check lists are slightly different :

Repairing a hole in an acoustic side

I have a lot of tools. There are so many different jobs I do on guitars I need a lot of tools. Most I buy, many I have to modify and a few I make.

This little clamp I made for a specific job, it doesn't get a lot of use but when I need it it's the only thing that will do.




Its made from a small piece of Australian Blackwood that I had around the workshop and an old kluson style guitar tuner. I like using guitar parts to make tools - it feels right that old guitar bits can help fix damaged guitars. A bit like donating your organs.



This guitar is unusual - it was hand made in London by a small maker who only ever made a few instruments. It is made entirely from recycled wood. It has the most balanced, lively and sensitive sound i have ever heard from a guitar.

It was brought to the workshop by its very proud owner who is clearly deeply in love with his guitar http://morganmusic.co.nz/vff/.

It needed a re-fret, a repair on a minor split in the top and a hole in the side - which is where the little clamp comes in.


The back and sides of this guitar are made of solid walnut. Solid wood has a much better resonance than ply but isn't as strong and breaks much more easily.

One small piece of wood was still hanging on to the damaged area and I found the other pieces inside the instrument. I decided to strengthen the area by putting a patch on the inside. I made this patch from koa simply because its a strong hardwood and I happened to have a suitable piece in the workshop from an old ukulele top - another example of organ donation.

I removed the piece that was still attached with tweezers and glued it to the inside of the koa patch. This piece of the side covers about 2/3 of the hole. I drilled a 1mm hole in the koa just above the piece of side and passed an old guitar string through it (recycling again). This way I can align the splintered piece of side and keep it flush to the side of the body as well as attach the patch all in one process.

Its then a case of applying the glue and fitting the patch. The string passes through the hole in the post of the tuner and I can tighten it up.


Once the glue has dried the clamp is removed and the remaining splinters are glued in place like a jigsaw. The patch gives them something solid to be glued to. Then its a case of touching up the finish and the job's done.

I was sorry to see this guitar go - I cannot remember playing a better sounding guitar. I got Bill in from next door to have a listen, he's an experienced sound engineer http://www.labstudio.co.nz/ and really knows guitars.

He didn't want to put it down either.

Pickup winding

I often have people bringing me faulty pickups. Sometimes it turns out there's just a loose wire and simply needs re-soldering. But sometimes the pickup needs re-winding.
With humbuckers its only usually one coil in which case I can measure the working coil and match the re-wind to it.
Its more common that I get Fender single coil pickups with faults. Older fender pickups can have problems with the insulation on the windings breaking down and the pickup looses its power and becomes thin and weedy sounding.





This is my winding machine. It lives in the corner of the workshop and a lot of customers comment on it.
It isn't possible to wind completely by hand as there are 7500turns on an old Strat pickup and more on a hot one.



The pickup bobbin attaches to the rotating spindle on the front of the machine (white).


The wire is very fine - its about as thick as hair and more brittle as ist made of copper. It's not cheap - the thinner it is the more expensive. I have a few guages for different pickup sounds.




The wire passes over a series of pulleys to tension it.


The machine has a counter with a cut off which stops winding when it gets to the correct number of turns.


so here's the finished product - an old Strat pickup restored to its former glory.

Gallery of Horrors

I see a lot of severely damaged instruments in my work. People are often amazed at what can be fixed and how good a guitar can be afterwards.
So here are some pictures of what can happen - but be warned, this is not for the faint hearted. This is just a small sample of what I see - I should take more pics.
All the guitars here were successfully repaired, returned to their owners and are doing fine.
